If Selena Gomez is trying to shed her little girl image, then posing for the cover of March's Cosmopolitan should definitely do the trick!

Justin Bieber's 19-year-old girlfriend, showing off major cleavage in a low cut Nanette Lepore floral dress, dished about her relationship with the "Baby" singer.

Gomez tells the mag:

"I’m just like every 19-year-old girl. If you’re in love, you’re in love to the fullest, and you just want to go to the movies, hang out, and be as normal as possible. I’m fortunate that I’ve found someone who has that philosophy.”

Now about all those racy headlines sharing the cover with Selena ...

Sexy, indeed! In case you were wondering, Selena is sporting Ariel Gordon Jewelry.
